Circled numbers are waveform references.
The components identi
fi
ed by shading and
!
symbol are critical for safety. Replace
only with part number speci
fi
ed.
The symbol
indicates a fast operating fuse and is displayed on the component
side of the board. Replace only with fuse of the same rating as marked.

Le symbole
indique une fusible a action rapide. Doit etre remplace par une
fusible de meme yaleur, comme maque.
NOTE: The components identi
fi
ed by a red outline and a mark contain con
fi
dential
information. Speci
fi
c instructions must be adhered to whenever these components
are repaired and/or replaced.
See Appendix A: Encryption Key Components in the back of this manual.
All capacitors are in

F 50WV or
less are not indicated except for electrolytics and tantalums.
All electrolytics are in 50V unless otherwise speci

ed.
All resistors are in ohms. k

All variable and adjustable resistors have characteristic curve B,
unless otherwise noted.
Readings are taken with a color-bar signal input.
Readings are taken with a 10M
digital multimeter.
Voltages are DC with respect to ground unless otherwise noted.
Voltage variations may be noted due to normal production
tolerances.
